To all whom it may concern:

Be it known that I, DAVID Gr. JOHNSTON, a citizen of the United States, residing at Clayworks, in the county of Webster and State of Iowa, have invented a certain new and useful Frame for Openings in Buildings, of which the following is a specifica tion.

'Ihe object of my invent-ion is to provide a frame of simple, durable and inexpensive construction, made out of a single piece of structural channel bar for the purpose of forming a frame for window and door openings in buildings particularly silos which may be readily and easily placed in position and firmly and securely held therein, and further to provide means whereby said frames may be readily and easily placed in .building material and after being so .placed may be firmly and securely held therein by pouring concrete in the spaces provided for it at the sides of the frame, and also to provide means whereby said frames may be used -for connecting strengthening and reinforcing wires or rods in the walls of the building.

My invention consists in certain details, in the construction, arrangement and combination of the various parts of the device whereby the objects contemplated are attained, as hereinafter more fully set forth,

pointed out in my claims and illustrated in the accompanying drawings, in which- Figure l shows a perspective view of a frame embodying my invention. Fig. 2 shows a vertical, central, sectional view of same, and F ig. 3 shows a horizontal, sectional view of same with the adjacent portions of a wall shown in position therein.

Referring to the accompanying drawings, the body portion of the frame isseen to be composed of a single piece of structural channel bar. The flanges of the channel bar are cut at the corners so that the central portion of the channel bar may be bent to thereby produce a frame composed of a the channel bar at 16 projecting beyond the flanges. This is bent down over the adjacent body portion of the channel bar 12 as shown 1n Fig. 2, and connected by rivets 17.

Secured to the centraly portion of the body portlon 12 at each side are two spacing and anchoring rods 18, t-he ends of which are extended through the part 12 and secured thereto, and the central portions of said rods stand spaced apart from the side 12 and lie parallel with it. These rods extend outwardly from the parts 12 of the frame handle about half the distance ofthe width of the iianges 13 as clearly shown in Fig. 2. Qn the interior ofthe frame, I have provlded sheet metal stops 19 riveted in position for engaging a door or window placed in the frame.

In Fig. 3 o f the drawings, I have illustrated a portion of a building wall 20 in position between the flanges 13 of th'e frame and 1n said wall are the reinforcing wires or rods 21 connected with t-he rods 18. In said figure the dotted lines 22 represent the division line between the wall proper and the concrete filler poured between the wall and the frame, the said concrete filler being indicated in said figure by the reference numeral 23.

In practical use it is obvious that the frames may be manufactured at a minimum of expense and that they strong and durable when placed in position. The spacing and anchoring rods 18 perform several functions, first in laying up the main walls vrelative 'to the frames. The building material such as brick, tile, or concrete is held spaced apart from the body portions of the sides 12 by means of said rods, these providing a space to receive concrete. a convenient anchorage and reinforcing wires 21 which may be tied to said rods during the construction of the wall. After the wall has been completed up to the top of the frame, the operator then pours concrete in wet condition into the space between the walls and the sides of the frame so that said concrete material completely lls all of the space between the wall and frame, thus making it air tight and preventing the entrance of moisture which would tend to rust the metal, and at the same time firmly securing the frame to the concrete by means of the rods 18, and

for strengthening will be extremely also firmly securing the reinforcing wires 21 to the ro crete has will be pr wall and tl flanges will also the frame itself will be held perfectly all ordinary strains tures are subjected. I claim as my invention- A l. A frame f composed of channel tending outwardly, said 'frame nel bars secure channel bars at points sp from parallel thereto, sai signed to rest adjacen o hold the same sp between building and t or openings in rods on each side of spaced apart from t the flanges of the chanthe channel bar and also to serve for the d to the central portion of the attachment of anchoring rods.

d rods being det to the'frame of the Witnesses:

from the central portion of the channel ds 18. Therefore when the conbars and also to serve for the attachmentI set and hardened, a perfect joint of anchoring rods.

ovided between the frame and the 2. A frame for openings in buildings, -e concrete material between the composed of channel bars with the anges .strengthen and reinforce extending outwardly, rods on each side of in such a manner that it` said frame between the flanges of the chanrni and true against nel bar secured to the central portion of to which said strucsaid channel bar parallel thereto at points spaced apart from said central portion at a distance less than the width o the flanges,

buildings, said rods being designed to rest adjacent to bars with anges exthe frame of a buildinlg and to hold the same e central portion of DAVID G. JOHNSTON.
